Accumulations began on February 16, 2018, or on the approximate leafout date for a specific orchard crop.

*Next week’s predicted ET is based on historical averages for the CIMIS station location.

Estimates are for orchard floor conditions where vegetation is managed by some combination of strip applications of herbicides, frequent mowing or tillage, and by mid and late season shading and water stress. Weekly estimates of soil moisture loss can be as much as 25% higher in orchards where cover crops are planted and managed more intensively for maximum growth.
